24、tection provided by the integral design of rotating electrical machines (IP code) Classification 1 Scope and object This International Standard applies to the classification of degrees of protection provided by enclosures for rotating electrical machines. It defines the requirements for protective e
25、nclosures that are in all other respects suitable for their intended use and which, from the point of view of materials and workmanship, ensure that the properties dealt with in this standard are maintained under normal conditions of use. In certain applications (such as agricultural or domestic app
26、liances), more extensive precautions against accidental or deliberate contact may be specified. This standard gives definitions for standard degrees of protection provided by enclosures applicable to rotating electrical machines as regards the: a) protection of persons against contacts with or appro
27、ach to live parts and against contact with moving parts (other than smooth rotating shafts and the like) inside the enclosure and protection of the machine against ingress of solid foreign objects; b) protection of machines against the harmful effects due to ingress of water. It gives designations f
28、or these protective degrees and tests to be performed to check that the machines meet the requirements of this standard. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 60034. For dated refer
29、ences, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of IEC 60034 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated referenc
30、es, the latest edition of the normative document referred to applies. Members of IEC and ISO maintain registers of currently valid International Standards. Page4 EN600345:2001 !This standard does not specify: degrees of protection against mechanical damage of the machine, or conditions such as moist
31、ure (produced for example by condensation), corrosive dust and vapour, fungus or vermin; types of protection of machines for use in a potentially explosive (dust, vapour) environment. “ IEC 60034-1, Rotating electrical machines Part 1: Rating and performance * IEC 60034-6, Rotating electrical machin
32、es Part 6: Methods of cooling (IC code) 3 Designation The designation used for the degree of protection consists of the letters IP followed by two characteristic numerals signifying conformity with the conditions indicated in the tables of clauses 4 and 5 respectively. 3.1 Single characteristic nume
33、ral When it is required to indicate a degree of protection by only one characteristic numeral, the omitted numeral shall be replaced by the letter X, for example IPX5 or IP2X. 3.2 Supplementary letters Additional information may be indicated by a supplementary letter following the second characteris
34、tic numeral. If more than one letter is used, the alphabetic sequence shall apply. 3.2.1 In special applications (such as machines with open circuit cooling for ship deck installation with air inlet and outlet openings closed during standstill), numerals may be followed by a letter indicating whethe
35、r the protection against harmful effects due to ingress of water was verified or tested for the machine not running (letter S) or the machine running (letter M). In this case, the degree of protection in either state of the machine shall be indicated, for example IP55S/IP20M. The absence of the lett
36、ers S and M shall imply that the intended degree of protection will be provided under all normal conditions of use. 3.2.2 For air-cooled open machines suitable for specific weather conditions and provided with additional protective features or processes (as specified in clause 10), the letter W may
37、be used. 3.3 Example of designation IP 4 4 Characteristic letters First characteristic numeral (see table 2) Second characteristic numeral (see table 3) _ * A consolidated edition 10.2 (1999) was issued comprising IEC 60034-1 (1996) and its amendments 1 (1997) and 2 (1999).

38、ees of protection First characteristic numeral 4.1 Indication of degree of protection The first characteristic numeral indicates the degree of protection provided by the enclosure to persons and to the parts of the machine inside the enclosure. Table 2 gives, in the third column, brief details of ob
39、jects which will be excluded from the enclosure for each of the degrees of protection represented by the first characteristic numeral. The term excluded implies that a part of the body, a tool or a wire held by a person, either will not enter the machine or, if it enters, that adequate clearance wil
40、l be maintained between it and the live parts or dangerous moving parts (smooth rotating shafts and the like are not considered dangerous). The third column of table 2 also indicates the minimum size of solid foreign objects which will be excluded. 4.2 Compliance to indicated degree of protection Co
41、mpliance of an enclosure with an indicated degree of protection implies that the enclosure will also comply with all lower degrees of protection in table 2. In consequence, the tests establishing these lower degrees of protection are not required, except in case of doubt. 4.3 External fans The blade
42、s and spokes of fans external to the enclosure shall be protected against contact by means of guards complying with table 1. Table 1 Test requirements for guards Protection of machine Test IP1X 50 mm sphere test IP2X to IP6X Finger test For the test, the rotor shall be slowly rotated, for example by
43、 hand when possible. Smooth rotating shafts and similar parts are not considered dangerous. 4.4 Drain holes If the machine is provided with drain holes, the following shall apply: drain holes intended normally to be open on site shall be kept open during testing; drain holes intended normally to be
44、closed on site shall be kept closed during testing; if machines with protection IP3X or IP4X are intended to be run with open drain holes, the drain holes may comply with protection IP2X; if machines with protection IP5X are intended to be run with open drain holes, the drain holes shall comply with
45、 protection IP4X.
